For centuries, interstellar prospectors had searched for the fabled worlds of the Three Kings, the lost El Dorado of the galaxy. But none had succeeded. Only the mad cyborg Prophet, Ishmael Hand, had ever seen the mysterious system, and he had refused to reveal its location before vanishing forever into history. Then a starfaring evangelist - Doctor Karl Woodward - found it, only to disappear in turn.

Now a new group of explorers must follow the trail that Woodward blazed. A spacegoing salvage team, desperately in debt after a violent alien menace ruins a lucrative assignment and decimates the group, is hired to follow the clues Woodward left behind.

Fearing pursuit by their former backers, the group heads off for the ultimate salvage operation. By hook or by crook, they will find the Three Kings- if the galactic underworld's repo men don't get them first!
